Sleeping Bear Heritage Trail

The Sleeping Bear Heritage Trail is a point-to-point multi-use route from the Bar Lake Road access at the north end of Empire to Bohemian Road (CR-669). Plan on about 20 miles one way; one current park trail page says 22, while other park and trail information and the mapped corridor support about 20. It is mostly paved, with compacted stone through the Port Oneida Rural Historic District and roughly three miles on signed Glen Arbor streets. This is a big day on foot, not a loop, so arrange a ride at the far end or choose a shorter section.

The trail has several parking areas, so you don't have to do the full line. Glen Arbor to the Dune Climb is a relatively flat four-mile stretch. The Empire approach has more climbing, while the northern section adds historic farms and gravel. Walking the whole route takes most of a day; allow roughly eight to ten hours with breaks. No end-to-end walking time is published, so treat that as a planning estimate, not a promised pace.

From Bar Lake Road the paved path winds through a wooded valley beside Voice Road. The first 1.5 miles climb steadily, then short pitches reach 10–12% near the M-22 and M-109 junction. The next stretch runs beside M-109 toward Pierce Stocking Drive. Traffic can miss trail users at the scenic-drive entrance. North of there, the steep descent nicknamed “The Bear” drops about 12% to Greenan Road, with a sharp turn at the bottom and a tough climb coming back. Take that section slowly, especially on a bike.

The route passes the Dune Climb and continues through woods toward Glen Haven, opening to low dunes near the historic village. The Glen Arbor–Dune Climb section is among the flatter parts. Between Glen Haven and Glen Arbor, the path passes through D.H. Day Campground and uses a campground road and seasonal road where vehicles may be present. A 2015 windstorm knocked down many trees that once shaded the approach, and low ridges along the wetlands mark old Lake Michigan shorelines.

At Forest Haven Road the separate path ends; the marked route continues for about three miles on village streets to the Crystal River access. This is the least trail-like part of the trip: it crosses a busy summer village with cars, bikes and pedestrians, so follow the markings and use the bike lanes. Near Crystal View Road, visibility is limited around a curve; after crossing M-22 by the Homestead, the trail climbs about 8%.

North of Crystal River, a roughly 500-foot boardwalk crosses wetland before the trail enters forest and then farm country. In the Port Oneida Rural Historic District, the pavement changes to compacted stone to fit the old agricultural landscape; loose gravel or washouts can make the steeper bits less comfortable. The route passes Charles Olsen Farm, Port Oneida School and Kelderhouse cemetery and farm. Farther north it crosses Narada Lake on a boardwalk, where ducks and loons are sometimes visible, then passes North Unity School before ending at Bohemian Road. The extra mile on the dirt road to Bohemian Beach is outside this trail route.

The park describes this as a multi-use route for walkers, cyclists, skiers, strollers and wheelchair users, but the steep grades and the compacted-stone section mean accessibility varies by stretch. Bar Lake Road has a gravel lot, vault toilet and bike repair station; no water is listed there. There are more facilities at other access points, but don't assume every trailhead has water. Pets are allowed on the trail except from December 1 through March 31.
